More potential search layers rather than pointer indirection. But I
doubt this is a bottleneck in very many programs. So I would more
concern myself first with quickly writing correct code.
I should add that when object access time matters and the object is
accessed repeatedly, a common solution is to bind it to a local name
*once* and then access it via the local (which is the fastest way
possible for CPython and, I expect, for other implementation). This
works for all slower access methods.
